i have been browsing ebay and found this

tuning module click here!!



has anyone tried it, i will put my hand up and say i have purchased one just to see if i feel any difference when the car is full warmed up with it.

what they are saying is, it signals the ecu that there is constant cold air (like morning start) and therefore causes a richer mixture of air/fuel, that makes it respond alot better and giving extra bhp and torque.

suppose its worth ago for £4

once i have recieved and fitted i will give the verdict, s**t thing is it dont come as a plug just 2 metal wires which go into 2 pins in plug also i take it its the maf sensor plug it uses

I wouldn't fit it, Know a few people who have and caused noting but problems, the worst being it caused to much fuel and trashed the cat. This was on a zs not an st though.
To be honest if you want power gains they are not going to come cheap. If you do fit it keep us updated with what happens. Also they are only resistors that you can get from maplins for 20p

I would stay well clear with messing with the ECU and giving it false signals. From going into Ford and seeing the experimental engines and what little things can make massive problems... it is a big no no for me.

Good Luck with it.

One big way to ruin a perfect car working prob , throw it away not worht all the problems or the time and effort fitting it , just still mods like induction kit exhaust dream science

Yep, seriously, SERIOUSLY don't fit it.
It will pump loads of fuel into your cat and kill it.

If I were u I wouldn't buy or fit this to ur car probably other things better for ur car

Fitted one to my mates ZS before and I think it was the engine management light came on. Made no difference to performance either. I chose not to fit it to the ST based on this

best place to put it is under your front wheel and run over it

These have been around for years, and the best place for them is the bin....

The mod itself is a small resistor that tells your engine control unit (ECU) that all of the air coming into the engine is cold and therefore dense and packed with oxygen.

Noooo, if you are going to tell a fib to the engine, you will need a good memory .
